I absolutely love the chemistry between them. Rio isn't the brightest bulb but I'm glad she has someone like Ayato. I feel he can really take care of her and he's respectful of her despite how weird she is. I think it's really sweet and why I like Ayato so much as a main love interest. A lot of other love interests in ero-manga can be a little inconsiderate but he just seems the guy to love so much once he finds the one and it really shows how well he's portrayed here. I can't wait for the next chapter, I want these idiots to be happy! ;w;
